Why area of rectangles matters
Understanding how to find the area of rectangles is a key skill for 11+ Maths. It helps children solve real-life problems and builds confidence with geometry questions.
How to calculate area
To find the area of a rectangle, multiply the length by the width. Both measurements must be in the same unit, such as centimetres or metres.
Worked example
Step 1: Measure the length. Suppose it is 5 cm.
Step 2: Measure the width. Suppose it is 4 cm.
Step 3: Multiply length and width: 5 cm × 4 cm.
Step 4: Calculate the answer: 20 cm².
Why practice helps
Regular practice with area questions helps children recognise question types and avoid common mistakes. It also prepares them for more complex problems in the 11+ exam.
Key insight: Understanding area calculations is a fundamental skill that appears in many 11+ Maths questions. Mastering this early gives children a strong foundation for geometry and problem-solving.
